I'm sure I'll figure it out. I think it's only loading available categories into the $categories variable.

*edit*
I figured it out. In categories.php I commented out:

$search_condition[] = "$sql_tbl[categories].avail='Y'";

I wouldn't do that if you have disabled categories though. I have no idea where else $search_condition is used. But for me, it fits my needs.

I had to put back the if statements in categories.tpl.
